Hello there,

I was warned. However during testing the engine 9400 revs with the os ax 120 with a 16x8 prop, the backplate exploded and totally desintegrated. The parts made 4 inch holes in the field. Lucky no one got hurt. Now I know again why not to be in the path of a turning prop. So again, do not use the supplied spinner. They are dangerous.
I now placed the fliteskin one. Fits exactly, but at a cost. $ 125 to be exact. But worth every dollar. Attach pictures didn't work today, but I'll try again later.

Regards,

Eric Schumacher, Netherlands
